BCM50 Installation and Maintenance Guide
To connect the cables
1
Rotate the power supply retention clip so that the power supply jack is clear.
2
Connect the power supply cord to the main unit.
3
Rotate the power supply retention clip to lock the power supply cord in place.
4
If the system has a UPS, connect the USB cable to the USB port on the main unit.
5
If the system uses the external Music Source port, connect the music source cable to the Music
Source port on the main unit.
6
Connect the expansion cables or LAN cables to the expansion ports on the main unit. For
expansion cables, make sure you connect the cables to the expansion ports from which they
were removed. This ensures the same line and extension numbering.
7
If the main unit is a BCM50a or BCM50e, connect the Ethernet cable or ADSL line to the
WAN port and the Ethernet cables to the Router card LAN ports.
8
Connect the Ethernet cable to the LAN port.
9
Connect the 25-pair cable to the RJ-21 telephony connector on the front of the main unit.
10
Secure the RJ-21 connector to the main unit.
If you are using a straight RJ-21 connector, use the two screws on the sides of the connector to
secure it.
If you are using a right-angle RJ-21 connector, use the screw on the left side of the connector
to secure the left side of the connector. To secure the right side of the connector, use a cable tie
to fasten the 25-pair cable to the anchor on the main unit.

Continue to the next step,
“To return the BCM50 system to operation”
.
To return the BCM50 system to operation
1
Check the Power and Status LEDs on the main unit. After the BCM50 has finished starting up,
both LEDs should be lit solid and green. If either LED is not lit solid and green, there is a
problem with the main unit. Refer to
“System status LEDs” on page 59
for a detailed
description of the LED states.
2
If this system has a expansion unit, check the Power and Status LEDs on the media bay
module (MBM) that is inserted in the expansion unit. Both LEDs should be lit solid and green.
If either LED is not lit solid and green, there is a problem with the MBM or the expansion unit.
Refer to
“Media bay module LEDs (expansion units only)” on page 64
for a detailed
description of the LED states.
3
If this system has a second expansion unit, check the Power and Status LEDs on the second
MBM.
Warning:
Leakage currents
You must connect the power cord to a grounded outlet before connecting the
telephony and data networking cables to the system.
